Is Huangqi Danggui oral liquid really useful for regulating qi and blood?

Huangqi Danggui oral liquid can be used to regulate qi and blood, but the effect is suitable for people. Chinese medicine is that one person regulates everyone's qi and blood. Generally, one formula is used for decoction (seven patches and one course of treatment), and Chinese patent medicines are not used much. Personally, I think it is necessary to regulate qi and blood by consulting professional directors, Chinese medicine practitioners and self-decoction and oral administration.
